INTERMEDIATE CARBTER FOR CANE-SUGAR MILLS.

Application filed March 23, 1922, Serial No. 546,195.

To all whom it may concern:

Be it known that I, JOSEPH MEINECKE, a

citizen of the United States, and a resident structions,combinations and mode of opera tion herein described and claimed.

An object of the invention is to provide an improved intermediate carrier or cane chute for transferring the bagasse from one macerating mill to another,

A further object of the invention is to provide an intermediate carrier which is widened at the summit to facilitate the passage of the bagasse across.

Other objects and advantages will appear in the following specification, reference being had to the accompanying drawings, in which:

Fig. 1 is a plan view illustrating the widened intermediate carrier,

Fig. 2 is a side elevation of the intermediate carrier, and

Fig. 3 is a detail cross section on the line 33 of Fig. 2.

.This invention is an improvement on the cane sugar mill disclosed in my Patent 1,401,095, granted December 20, 1921. The purpose of both inventions is to provide a carrier for conveying bagasse from one sugar cane macerating mill to another. The carrier consists of a chute through which the bagasse is pushed from one mill to the other. The chute is of such a construction that no injury can result thereto from the great pressure under which the bagasse is discharged from one of the mills.

The old construction disclosed in the patent referred to and repeated here for the purpose of illustration, comprises the chute generally designated 13. This chute includes a bottom plate 14. disposed at an angle of from 30 to 15 degrees (preferably 45 degrees) from the horizontal, and another bottom plate 15 which is disposed preferably at an angle of from 30 to 4:5 degrees from the horizontal, eliminating all moving parts so that there can be no delay due to the breakage of chain slats, etc. The bottom plate (of which 14: and 15 are parts) bends cover 25.

at the summit 9 which must be crossed by the bagasse upon being discharged by the mill 11 on its Way to the mill 12.

The intake side 15 of the chute li-lhas scrapers 22 which engage the expressing rollers of the mill 11 so as to remove any of the substancewhich would otherwise adhere to the surfaces and be carried around.

The intake or receiving side 15 is of lessinclinatlon than the'discharge sidelt. "In I other words, the latter (14:), is steeper-than the former (15). The steepness of the dis-' charge side 14 facilitates the expulsion of the mass of bagasse after it crosses the summit 9'.

Bars 23 carry plates to which the scrapers" 22 are attached, Each ofjthe scraperbars has a lever 20 at each end. Rods 21 with turn buckles are attached to the ends of the levers and to fixed parts of theframe. The

22 in respect to the expressing rolls"in the mill 11.

The receiving end of the chute 13 has a This cover may extend as far toward the summit as conditions may require. The cover is hinged at 24 so that it may be lifted. It carries clips 26 at the free endto rest on the edges of the chute sides. Other details of construction of the chute, such as the side plates at the receiving and discharge ends, bracing means, etc., need not be described here, since they have'no direct bearing on the improvement, which resides wholly in the middle chute structure. Fig. 1 shows the chute 13 to have been widened at 27 across the summit 9. In other words, the widest part of the chute is across the ridge or summit. From this point, the sides converge or taper until they assume the normal width at the mills 11 and 12.-

The walls or sides of the chute slant outwardly or diverge at 28. The widening of the chute at the summit in the manner described has been found to cause a more efficient operation than the straight-sided chute of the co-pending application.

Pipes 30, perforated underneath, sprinkle the bagasse with water as it passes the summit 9. The water aids maceration. Obviously, the widened chute summit lengthens the sprinkling area. A better penetration of the bagasse by the water is secured because of the thinning of the strata of bagasse when crossing the summit. This thinning of the bagasse strata is caused by the spreading of the mass when it reaches the widened zone 27.

The bagasse is ejected from the mill 11 at a given speed. The mass moves up the incline 15 at a given speed. Obviously, the

rate of movement of the mass diminishes as the chute Widens toward the summit 9 and this slackening of the speed of the mass is an additional aid to the penetration thereof by the water from the pipes 30.

I claim 1. An intermediate feed chute for sugar mills comprising oppositely inclined portions laterally widening toward the summit to cause a spreading and thinning of a bagasse mass moving up one incline.

2. In combination with adjacent sugar cane mills, a chute between the two embodying a gradually widening portion for reducing the depth and rate of movement of a bagasse mass discharged by one mill.

3. A chute to be disposed between adjacent mills, having portions inclining from and widening laterally toward a summit.

.4. A chute to be disposed between adjacent mills, comprising a bottom plate inclining from and widening laterally toward a summit, and side plates inclining outwardly.

5'. The combination of a pipe for discharging macerating fluid, and a chute including portions inclining to a summit sub stantially beneath the pipe, and laterally widening toward said summit to cause a reduction of the depth and rate of motion of a bagasse mass moving toward said summit and thereby secure a more thorough penetration of the bagasse by said fluid.

6. An intermediate feed chute comprising oppositely sloping bottom portions disposed at different inclinations and widening toward a summit, side walls flaring upwardly, and a cover for one portion of the chute, hingedly mounted and carrying means to rest on the edges of adjacent sides.

7. In combination with adjacent sugar cane mills, a chute extending from one to the other, the ends of the chute corresponding in width to the length of the rolls of the mills but laterally wider at the middle portion of the chute than at its ends.

8. In combination with adjacentsugar cane mills, a chute extending from one to the other including inclined portions united at the summit,'the ends of the chute corresponding in width to the length of the rolls of the mills, the inclined portions gradually widening laterally until'the place of union at the summit is reached.
